Paris Jackson Moves, Hires Armed Security for Protection from Isaac Kappy

Paris Jackson is taking extreme measures to protect herself from Isaac Kappy, the actor who allegedly choked her, including amping up her security and moving out of her home ... TMZ has learned.

Sources familiar with the case tell us Paris has continued getting text messages from Kappy, and they're rambling and downright scary. We're told the tone of the texts is similar to the letters Kappy sent to Seth Green -- loving and caring, but also sounding like he's coming unhinged.

We're told Paris initially responded to Kappy's texts because she feared he was suicidal and wanted to be supportive.

TMZ broke the story ... Kappy was good friends with Paris and Seth up until last month when he allegedly choked Paris during a game night party. He also posted videos accusing Seth and his wife of being pedophiles, and intimated he was prepared for a shootout with police.

Our sources say Paris isn't taking any chances. We're told she's relocating, and now has armed security with her at all times. She's also blocked his number.
